We need to deal with editing articles. Of course we can add new routes manually, like this:
<code>Route::get('/articles/{id}/edit', 'ArticleController@edit');</code>
Let’s use artisan
’s route:list
from the command line to view our current routes:
<code>php artisan route:list</code>
In the case of RESTful compliance, it may be a good choice to directly use laravel's resource
route. However, we will remove all routes and only add the only one:
<code>Route::resource('articles', 'ArticlesController');</code>
Use <code>php artisan route:list</code> again to view the routes, wow, a bunch of routes that meet our expectations are generated. Look at each item carefully.
Now add method in controller:
<code> public function edit($id) { $article = Article::findOrFail($id); return view('articles.edit', compact('article')); }</code>
Create View Now
<code>@extends('layout') @section('content') <h1 id="Edit-article-gt-title">Edit: {!! $article->title !!} </h1> <hr> ...</code>
Okay, I admit that these codes are all copied from create.blade.php
and modified a bit. The question is do we need to repeat them? We will deal with this issue later, now let’s look at the form submission issue. In the routing <code>php artisan route:list</code>, look again and use the PATCH
method. Let’s modify the view:
<code>{!! Form::open(['method' => 'PATCH', 'url' => 'articles/' . $article->id]) !!} </code>
Visit /articles/1/edit
in the browser, check the source code, and find that laravel automatically generates the hidden field of _method=PATCH
.
The first problem is that we edit the article, but the information of the article is not displayed. Let’s modify the view:
<code> {!! Form::model($article, ['method' => 'PATCH', 'url' => 'articles/' . $article->id]) !!}</code>
OK, everything's ok, except that the published_on
field is still set to the current date, we'll deal with that later.
Now add method in controller:
<code> public function update($id, \Illuminate\Http\Request $request) { $article = Article::findOrFail($id); $article->update($request->all()); return redirect('articles'); }</code>
We also need to verify during the modification process. Let us reuse our Request class and rename CreateArticleRequest
to the more general ArticleRequest
. Don’t forget to modify the parameters in the store
method.
<code> public function update($id, Requests\ArticleRequest $request) { $article = Article::findOrFail($id); $article->update($request->all()); return redirect('articles'); }</code>
The remaining problem now is that our new and edit use most of the same code, such as displaying errors, but there are two copies of them, let's fix this problem.
We create a new file list.blade.php
directly under views/articles
, and copy the error handling code from create.blade.php
:
<code>@if ($errors->any()) <ul class="alert alert-danger"> @foreach($errors->all() as $error) <li>{{ $error }}</li> @endforeach </ul> @endif</code>
In create.blade.php
just replace the error handling code with the following statement:
<code>@include('articles.list')</code>
Let’s deal with the form code again. The form code is almost the same except for form
which is different from the submit button. We create a view articles/form_partial.blade.php
and copy the code
<code><div class="form-group"> {!! Form::label('title', 'Title:') !!} {!! Form::text('title', null, ['class' => 'form-control']) !!} </div> <div class="form-group"> {!! Form::label('body', 'Body:') !!} {!! Form::textarea('body', null, ['class' => 'form-control']) !!} </div> <div class="form-group"> {!! Form::label('published_at', 'Publish On:') !!} {!! Form::input('date', 'published_at', date('Y-m-d'), ['class' => 'form-control']) !!} </div> <div class="form-group"> {{--这里要设置变量,依据是编辑还是修改来改变,当然也可以不放置在partial中--}} {!! Form::submit($submitButtonText, ['class' => 'btn btn-primary form-control']) !!} </div></code>
Modify create.blade.php
<code>@extends('layout') @section('content') <h1 id="Write-a-New-Article">Write a New Article</h1> <hr> @include('articles.list') {{--使用我们添加的 illuminate\html 开源库--}} {!! Form::open(['url' => 'articles']) !!} @include('articles.form_partial', ['submitButtonText' => 'Add Article']) {!! Form::close() !!} @stop</code>
Modify edit.blade.php
<code>@extends('layout') @section('content') <h1 id="Edit-article-gt-title">Edit: {!! $article->title !!} </h1> <hr> @include('articles.list') {{--使用我们添加的 illuminate\html 开源库--}} {!! Form::model($article, ['method' => 'PATCH', 'url' => 'articles/' . $article->id]) !!} @include('articles.form_partial', ['submitButtonText' => 'Update Article']) {!! Form::close() !!} @stop</code>
The above has introduced the basics of Laravel 5 (11) - Subview and form reuse, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
